How to prevent the occurrence of tomato cavitous fruits?

The appearance of the cavitary fruit is ridged and the section is polygonal. Visible cavities can be seen when the fruit is cut, and some fruits have no edges but also cavities inside. The causes of hollow fruit are:

Poor fertilization, or excessive application of nitrogen fertilizer. If the concentration of hormone dipping is too large, or the flower buds are small when dipping into flowers, it is easy to produce hollow fruits. A fruit bulking agent was used, but the light was weak and the temperature was low.

The nutritional status of the plant does not meet the needs of fruit enlargement. If the night temperature is too high, the plant grows, and the photosynthetic products cannot be transported smoothly to the fruit, causing the fruit to be hollow.

The following measures are mainly used for the control of tomato cavitary fruit: first, variety selection.

Choose a multi-hearted DAO chamber or an early-maturing small-fruited type.

Edition varieties can avoid empty.

The Birth of the Fruit of the Power Cave.

Second, agricultural measures.

The temperature of the seedling stage 2 and 4 true leaves can not be lower than 12 continuously, and the night temperature is controlled at about 17, and the seedlings can be heated with ground ** or geothermal water; During the flowering period, it is necessary to avoid the harm of high temperature above 35 to fertilization and promote the normal development of the placenta. Rational use of auxin, do a good job of fruit thinning. From the first inflorescence of more than 50% of the flowers when flowering began to use auxin dipping flowers, after 3 days of dipping flowers, if you see that the ovary begins to expand, indicating that the fruit has been in place, you should choose 3 4 fruits in time, and the rest of the flowers and fruits are all thinned out to ensure the concentration of nutrients and prevent hollow fruits caused by malnutrition.

Strengthen the management of water and fertilizer in the late growth stage, and timely fertilizer supplementation to prevent premature plant aging.

Tomato hollow fruit refers to a fruit that has a cavity between the peel and the gelatinous pulp. Although the impact of tomato hollow fruit on yield is not too great, it will seriously affect the commerciality and reduce the economic benefits, which cannot but be paid attention to in production.

Tomato cavitation fruit is a physiological disease, and varieties with a small number of ventricles are prone to occur. In general, early-maturing varieties have a small number of ventricles. There are many reasons for the formation of tomato cavitation, such as improper time of hormone spraying, after spraying hormones on the calyx, peduncle and flower bud two days before flowering, the fruit development rate is faster than that of normal pollination, and it promotes maturity, but the placenta is more dysplasia leads to cavities in the ovary; or insufficient light, photosynthetic products are reduced, and the nutrients transported to the fruit are in short supply, and a cavity is formed; or the terrain is weak, large varieties that require a large amount of abar, the nutrition cannot keep up in the late growth stage, the carbohydrate accumulation is small, and there are also hollow fruits; or insufficient watering during the peak fruiting period; Or leave too much fruit, nutrients ** do not go up and form a hollow.

To control tomato cavitation, you can choose varieties with more heart chambers; Rational use of regulators, each inflorescence has 2 3 When the flowers open, spray hormones, and the concentration of anti-falling hormone is 15ppm-25ppm, do not repeat; Apply sufficient basal fertilizer, adopt formula fertilization technology, and reasonably distribute nitrogen, phosphorus and potassium; In the peak period of fruiting, timely chase enough fertilizer and water enough to meet the nutritional needs of tomatoes, and according to the characteristics of the variety, pinch the tips in time, so that the vegetative growth and reproductive growth of the plant can develop in a balanced manner.

How is it formed?

1. Formation of tomato hollow fruit.

The reason du:

First, poor fertilization, pollen formation when high temperature, insufficient light dao make the pollen not full, can not be fertilized normally, the right to make the internal development of the fruit incomplete formation and cause cavities;

second, too much nitrogen fertilizer is applied;

The third is that the amount of hormone dipping in flowers is too large, or the flower buds are young when dipping flowers, which are easy to produce hollow fruits.

2. Six points should be paid attention to to prevent tomato hollow fruits:

One is to choose varieties that are not easy to produce hollow fruits;

the second is to prevent planting with small seedlings;

Third, fertilizer and water management should be appropriate to avoid excessive fertilization, especially excessive nitrogen fertilizer;

Fourth, the correct use of dipping drugs to prevent the production of hollow fruits when handling young buds;

Fifth, the temperature of seedlings and fruiting period is not easy to be too high, especially to prevent the night temperature of seedlings from being too high;

Sixth, topping should not be too early.

Dear, it is an honor to answer your questions, effective measures to control tomato cavitation fruit Tomato cavitation fruit is caused by factors such as tomato pollen shrinkage or environmental stress, the following are effective measures to control tomato cavitation:1Suitable temperature:

Maintain the right growing temperature to avoid extreme weather conditions such as high temperatures, low temperatures and drought. 2.Moisture Management:

Reasonable watering to ensure that the soil is moist but not too much water. At the same time, pay attention to good drainage. 3.

Fertilization management: timely replenishment of sufficient nutrients, especially phosphorus, potassium and other trace elements. 4.

Managing the flowering period: Make the necessary pruning and adjustments during flowering to promote normal flowering and fruit set. 5.

Pest control and treatment: Regular inspection and take corresponding measures to prevent the invasion of pests and diseases. 6.

Spray-assisted pollination: When the weather is clear and windless, a sprayer can be used to spray fine pin and particulate matter onto crops to achieve the purpose of assisted pollen dispersal. The above methods can help reduce the incidence of hollow fruit in tomatoes, open the chain and improve yield and quality.

Causes of Tomato Cavitation:

1. Category selection. In general, tomatoes with early development have a small number of atria and a large fruit tomato with medium and late ripening have a high number of atrium, and tomatoes with a small number of atria are very prone to cavitation. Even if it is the same category, if the fruit has a late blooming spike, it will be easy to produce hollow fruit due to insufficient nutrient supply.

2. Environmental factors. Temperature and light interfere with the growth and development of tomato fruits, and underdeveloped fruits are prone to produce hollow fruits.

Temperature: When the temperature is slightly low or too high, it is easy to form hollow fruits, and greenhouse tomatoes with winter stubble and early spring stubble are very easy to produce hollow fruits due to slightly lower temperatures. Pollen is produced at a high temperature of 34 and lasts for a long time, making it very easy to produce cavitary fruits due to poor pollination and fertilization.

Light: If the tomato is not exposed to enough light after it is in full bloom and bears fruit, it will cause the growth to be unharmonious and form hollow fruit due to the decrease of photosynthetic products and insufficient nutrient transport.

3. Insufficient fertilizer and water. In the high yield period of tomato, middle and late growth, if the amount of watering and fertilizer is not uniform enough, hollow fruits will be formed due to insufficient nutrients. In addition, too much basal fertilizer application is also very easy to produce hollow fruits.

4. Hormone application. When using hormones such as 2,4-d or tomato to dip flowers, if the concentration value of the drug is too large, repeated dipping of flowers, etc., it is very easy to produce hollow fruits. Due to the fruit under the influence of hormones, its ovary is enlarged, and the development efficiency is faster than that of normal pollinated fruit, but the placenta is prone to hypoplasia, and then forms cavitary fruit.

Control measures for tomato cavitous fruits:

1. Moderate transplantation and colonization. In the process of seedling planting, it is not suitable to transplant tomato seedlings, because the rhizome absorbs nitrogen in the soil very strongly after seedling planting, it is very easy to cause the rapid development of fruits and the slow development of placenta and seeds, and then generate hollow fruits. Under normal circumstances, the seedling age of tomatoes in greenhouses in early spring is 70-90 days.

2. Effectively control the indoor temperature. Effective greenhouse light temperature is beneficial to fruit development. When farmers plant tomatoes for winter stubble and winter and spring stubble, they should be in the seedlings and the first.

In the first and second bract periods, light and temperature rise countermeasures should be moderately adopted to maintain the temperature of 20-28 during the day and 15-17 at night, so as to prevent the continuous occurrence of ultra-low temperature below 11.

Tomato cavities are formed due to bacterial infection and internal decay, and the control measures are to pay attention to the applicable temperature and water temperature.

The main reason is that the ground flour is not applied in time during the flowering and fruiting process of tomatoes, the sunlight is not sufficient, the pollination is not carried out in time, and the water replenishment is not sufficient. In the process of tomato flowering, it is necessary to do a good job in adding management, spraying nutrient solution in time, applying organic fertilizer, and increasing the fertility of the soil.

It may be that soil erosion is more serious, resulting in soil compaction; First of all, it is necessary to water regularly to ensure adequate nutrition, pay attention to the prevention and control of pests and diseases, and avoid light and wind.

Insufficient light may also be caused by too high temperature, pay attention to light, pay attention to adjust the temperature, and plant reasonably.

The first point is that it is very likely that there is a drought phenomenon, which must be paid attention to, the second point is that there are toxins in the soil that have begun to ferment, the third point is likely to be bad air, and the fourth point is that pesticides should be sprayed if you want to prevent it.

Mainly because the variety is relatively bad, and can not grow well, so there will be such a situation, and there is no timely absorption of nutrients in the soil, in this case we must pay attention to fertilization, so that the tomato can grow better.

It is necessary to apply fertilizer reasonably, strengthen management, plant reasonably densely, cultivate rice seedlings, and also choose high-quality varieties, which can also be sprayed with drugs for prevention and control, etc.

Should we weed often, and should we water frequently, or should we pay attention to pests and diseases, so that we can carry out reasonable control.

First of all, you can choose pest-resistant and drought-tolerant varieties to plant, and then maintain the temperature in the greenhouse at 20 degrees Celsius, the humidity at about 50%, and water and fertilize every day, so that you can prevent and control this situation in tomatoes.

Tomatoes, also known as tomatoes, are very nutritious and are a very common vegetable on our daily table. Due to the high yield of tomatoes and good economic benefits, many farmers grow tomatoes. However, tomatoes are prone to hollow fruits in the planting process, which affects the quality, so what are the reasons for the appearance of hollow fruits?

Tomato cavities are actually hollows in the fruit, mostly due to bad weather. After the tomatoes are flowering and fruiting, if they often encounter continuous rain and snow weather, it will be insufficient in light, the nutrients in the tomato fruit are insufficient, and the growth of the peel and the growth of the pulp are not coordinated, and it is easy to form hollow fruits. Or is it that the fertilization is not paid attention to, and more nitrogen fertilizer is applied, resulting in a lack of balanced fertilizer and nutrients, and the tomato plant grows more vigorously, but the nutrient accumulation of the fruit part is not enough, resulting in stunted development and hollow fruits.

There is also a lack of water and fertilizer in the planting of tomatoes, so the whole tomato will be malnourished and form a hollow fruit. Now that we know the causes of tomato hollow fruits, how can we prevent them? Let's take a look at the delicious food next.

1. Create good light and temperature conditions. When the seedling period encounters cloudy and weak light, the temperature should be appropriately raised during the day, and the temperature should be controlled at about 17 degrees at night. By artificially controlling the temperature, the tomatoes grow healthier. If the temperature is not reached, the tomatoes will grow very slowly.

2. Reasonable fertilization. Apply sufficient basal fertilizer, adopt formula fertilization technology, and reasonably distribute nitrogen, phosphorus and potassium; So that the tomatoes can get enough nutrients. Tomatoes can only grow if they are adequately nourished by rotten waiters, otherwise they are prone to malnutrition.

3. Ensure that water and fertilizer are sufficient. At the same time as giving sufficient water, it is necessary to fertilize reasonably, so that tomatoes get both nutrients and water. Only then can tomatoes thrive.

Although tomatoes are delicious, planting is not simple, and you must master the planting method in order to have the most hungry harvest.

1.Lack of a certain camp accompaniment to the empty cultivation score, book spine 2Not fertilized, 3Excessive nitrogen fertilizer content applied, 4Too much hormonal fertilizer is used, 5The quality of the flower pollen is not good and other reasons are caused by indiscriminate infiltration.

Causes of tomato cavitous fruits: 1. Reasons for the formation of tomato cavity fruits: First, poor fertilization, pollen formation is not full due to high temperature and insufficient light, and can not be inseminated normally, so that the internal development of the fruit is incomplete and causes cavities; 2. Nitrogen fertilizer is applied too much; 3. The dosage of hormone dipping in flowers is too large, or the flower buds are young when dipping flowers, which are easy to produce hollow fruits.

Six points should be paid attention to to prevent tomato hollow fruits: 1. Choose varieties that are not easy to produce hollow fruits; 2. Prevent planting with small seedlings; 3. Fertilizer and water management should be appropriate to avoid excessive fertilization, especially excessive nitrogen fertilizer; 4. Correct use of flower-dipping drugs to prevent hollow fruits when handling young buds; 5. The temperature of seedlings and fruiting period is not easy to be too high, especially to prevent the night temperature of seedlings from being too high; 6. Topping should not be too early. Hope mine can be helpful to you.

This is due to the fact that there are too few nutrients in the land when planting tomatoes, or it may be caused by the influence of the weather and overwatering.

It is very good that the humidity does not meet the requirements, the temperature does not meet the requirements, there is no spraying of pesticides in the hall, and there is a lot of stagnant water, which leads to root rot and no timely ventilation.

In late spring and early summer, tomatoes enter the growth period, at this time, both temperature and environment are conducive to the growth of tomatoes, many tomatoes appear hollow fruit, I don't know how to prevent and control. What are the control measures for tomato hollow fruit?

Tomato hollow fruit control measures.

1.Choose the right breed. According to the different stubble and market time of the solar greenhouse, the varieties that are not easy to produce hollow fruits are selected.

2.Correct use of dipping herbs. Tomato flowering should be used correctly for plant growth, generally before 11 a.m. In the summer and autumn high temperature seasons, when using dipping flowers, the concentration of spraying should be reduced accordingly.

3.Manage it properly. In the use of fertilizer, it is necessary to increase the application of Trim organic fertilizer, reasonably match nitrogen, phosphorus and potassium fertilizers to avoid excessive application of nitrogen fertilizer; In terms of water, the amount of watering and the number of days between should be determined according to different growth periods and soil moisture; Prevent colonization with small seedlings, and at the same time, the ventricle should not be plucked too early.

4.Improve light and temperature conditions. The temperature of seedlings and fruiting period should not be too high, especially to prevent the night temperature of seedlings from being too high.
